摘要

以2-丙醇为氢供体，氧化铝上氟化钾(50% wt.%)为碱，[Ir(COD)Cl]2为金属催化剂，18-冠-6为相转移剂，在82℃固液双相体系中，烷基芳基(杂芳基)酮的氢转移还原反应容易发生。酮:[Ir]: F−]:18冠-6的摩尔比为200:1:5:2。在HTR-PTC条件下，以73-84%的分离收率制备了烷基芳基和烷基杂芳基甲醇。

Iridium (I) and phase-transfer catalyzed hydrogen-transfer reduction of ketones using potassium fluoride on alumina as a base

The hydrogen transfer reduction of alkyl aryl (heteroaryl) ketones readily occurs at 82°C in a solid—liquid biphasic system when using 2-propanol as hydrogen donor, potassium fluoride on alumina (50 wt.%) as a base, [Ir(COD)Cl]₂ as the metal catalyst and 18-crown-6 as the phase-transfer agent. The molar ratio of ketone : [Ir] : F⁻] : 18-crown-6 was 200:1:5:2. A number of alkyl aryl, and alkyl heteroaryl carbinols have been prepared in 73–84% isolated yield under HTR-PTC conditions.

期刊介绍： Journal of Molecular Catalysis (China) is a bimonthly journal, founded in 1987. It is a bimonthly journal, founded in 1987, sponsored by Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, under the supervision of Chinese Academy of Sciences, and published by Science Publishing House, which is a scholarly journal openly circulated both at home and abroad. The journal mainly reports the latest progress and research results on molecular catalysis. It contains academic papers, research briefs, research reports and progress reviews. The content focuses on coordination catalysis, enzyme catalysis, light-ribbed catalysis, stereochemistry in catalysis, catalytic reaction mechanism and kinetics, the study of catalyst surface states and the application of quantum chemistry in catalysis. We also provide contributions on the activation, deactivation and regeneration of homogeneous catalysts, solidified homogeneous catalysts and solidified enzyme catalysts in industrial catalytic processes, as well as on the optimisation and characterisation of catalysts for new catalytic processes. The main target readers are scientists and postgraduates working in catalysis in research institutes, industrial and mining enterprises, as well as teachers and students of chemistry and chemical engineering departments in colleges and universities. Contributions from related professionals are welcome.
